Abstract

This invention relates to a target board for electrically sensing the penetration of darts and similar missiles that do not penetrate entirely through the target. More specifically, the invention relates to the construction of a target board that is adapted to be a sensing device to trigger an electrical scoring device not of this invention wherein an electrical trigger circuit is closed upon the impact of a pointed missile (12) partially penetrating the target board. A unique feature of this invention is that it allows the use of regulation-grade metal-pointed throwing darts of the type preferred by serious dart players, with no modifications made to the dart to accommodate the triggering of the target board circuit.
